KubeRay Operator Add-on

Ray is a framework for scaling AI applications written in Python. Ray consists of a core distributed runtime and a set of AI libraries for simplifying ML compute. Ray allows scaling applications from a laptop to a cluster.

KubeRay is a Kubernetes Operator that simplifies the deployment and management of Ray applications on Kubernetes. It is made of the following components:

  • KubeRay core, the official, fully-maintained component of KubeRay that provides three custom resource definitions, RayCluster, RayJob, and RayService
  • Community-managed components (optional): KubeRay APIServer, KubeRay Python client and KubeRay CLI

Please refer to KubeRay Operator documentation for detailed information.

This add-on installs the KubeRay Operator Helm chart.


import { Construct } from 'constructs';
import * as blueprints from '@aws-quickstart/eks-blueprints';

export class KubeRayConstruct extends Construct {
    constructor(scope: Construct, id: string) {
        super(scope, id);

        const stackID = `${id}-blueprint`;

        const addOn = new blueprints.addons.KubeRayAddOn();

            .build(scope, stackID);


To validate the KubeRay Operator installation, please run the following command:

kubectl get pods
